Abstract

The method and apparatus of the invention converts harmful heteroatoms such as halogens, nitrogen, sulfur and phosphorous in a heteroatom-substituted organic feed stream to less harmful materials by reacting with a reactive gas, such as steam, adjacent a reactive material which has been coated on a porous membrane. The reaction produces secondary products such as acid gases and/or that are neutralized or otherwise rendered innocuous by a reaction with the reactive material which coats the porous membrane. The solid products from the reaction are deposited onto the coating and can be periodically removed by means known in the industry. A gaseous effluent rendered substantially harmless passes through the porous membrane and is either vented or sent for further treatment by conventional means.
